Langbeinite, chemically known as Potassium magnesium sulphate, or ‘SulPoMag’ in farming circles, is a naturally occurring mineral deposited millions of years ago as ancient ocean beds evaporated. As the names suggest, Langbeinite contains high levels of three key plant nutrients: potassium, magnesium and sulphur. This water-soluble organic fertilizer will not affect soil pH, has a relatively low salt index, making it a good choice for chloride sensitive crops.
- Excellent source of potassium, magnesium and sulphur.
- Slow release fertilizer supports balanced crop nutrition over the entire season.
- Low salt index and chloride levels makes this a good choice for sensitive crops.
- Will not affect soil pH like other magnesium and sulphur fertilizers
